Drone footage captured this week shows a dramatic acceleration in construction activity at SpaceX's newly annexed 444-acre site near Starbase, Texas. RGV Aerial Photography noted the concrete poured since their first flyover just days earlier — a visible sign that SpaceX is moving fast on a facility whose exact purpose remains officially unconfirmed.
How did SpaceX acquire this land?
The 444-acre parcel went through two separate municipal actions in quick succession. On August 29, 2026, the Brownsville City Council voted unanimously to disannex the land, removing it from Brownsville's zoning jurisdiction. Less than a month later, on September 22, 2026, the city of Starbase formally approved voluntary annexation of the same property — effectively absorbing it into SpaceX's home municipality. The entire process, from council vote to annexation, took under four weeks.
What did SpaceX pay Brownsville to make this happen?
According to reporting from regional outlets, SpaceX committed $220 million to Brownsville in exchange for the disannexation. The deal is structured in two tranches: an initial $40 million deposit due within 30 days of the vote, earmarked for a potable water reuse project, and $180 million spread over approximately 18 months to expand the Southmost Regional Water Authority's brackish groundwater treatment plant. It's a substantial infrastructure investment tied directly to the land transfer.
Will rockets launch or be tested here?
No. SpaceX Vice President of Starship Legal and Regulatory, Sheila McCorkle, told the Brownsville City Commission explicitly that the 444-acre site will not be used for rocket launches or testing. McCorkle described the land north of Highway 4 — which is where this parcel sits — as being for SpaceX's "own use," while land south of Highway 4 is designated for vendors and subcontractors. That distinction is important: this is internal SpaceX infrastructure, not an expansion of the launch complex.
How far along is construction right now?
Further along than the timeline suggests it should be. Drone footage from September 11, 2026 — just 13 days after the original council vote — already showed heavy activity, with 51 to 53 foundation footings in place and rebar mats being assembled. A new dirt access road connecting to the port road had also appeared. By the September 25 flyover from RGV Aerial Photography, the pace had visibly intensified, with significantly more concrete poured in under two weeks. A 24-inch natural gas pipeline, designated "Port Pipeline 1," is also planned to reach the site, with a start date of October 1, 2026 — notably 8 inches larger in diameter than the pipeline currently supplying the launch site's LNG liquefaction plant.
What is SpaceX actually building there?
That's the open question. SpaceX has not publicly disclosed the facility's purpose, and McCorkle's comments to the city commission were deliberately vague. The infrastructure clues — large-scale foundation footings, a heavy-capacity natural gas pipeline, direct port access — have led observers to speculate about several possibilities: a dedicated powerplant, a data center, a manufacturing facility, or marine loading infrastructure tied to Starship hardware logistics. The oversized gas pipeline in particular has drawn attention, since it exceeds what the existing launch site requires. For now, the official purpose remains unconfirmed.
Construction at this pace — visible structural progress within two weeks of a municipal vote — suggests SpaceX had plans well developed before the annexation was finalized. What exactly gets built on those 444 acres will likely become clear as the foundation footprint takes shape over the coming months.
